LTER/HBR009: Precipitation and streamwater samples are collected once a month (or twice a month in summer) and sent to the University of Missouri Trace Substances Laboratory for analysis. Analyses are for Pb, Ni, Cd, Cu, Mn, Fe, and Zn. We are currently routinely sampling the reference watershed (6) and the ... recently clearcut watershed (5) in the Hubbard Brook Experimental Forest. Watersheds 2, 4, and 8 were studied for two-year periods in the late 1970's. Summary analyses are completed through 1988.

The Hubbard Brook Experimental Forest (HBEF) is a 3,160 hectare reserve dedicated to the long-term study of forest and stream ecosystems. Located in the White Mountain National Forest of New Hampshire, the HBEF was established in 1955 and is operated by the USDA Forest Service, Northeastern Forest Experiment Station.
